Description
CATO manufactures 1,2-Bis(3-chlorophenyl)ethyne under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
CATO supplies 1,2-Bis(3-chlorophenyl)ethyne (CAS 5216-30-8), a certified reference material (molecular formula C14H8Cl2, MW 247.12 g/mol) for analytical method development and quality control.
The molecular framework of 1,2-Bis(3-chlorophenyl)ethyne (C14H8Cl2) is characterized by chlorine substitution, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
